Lightweight (MMA)

The lightweight division in mixed martial arts contains different weight classes:

• The UFC's lightweight division, which groups competitors within 146 to 155 lb (66 to 70 kg)
• The Shooto lightweight division, which limits competitors to 145 lb (65.8 kg)
• The ONE Championship's lightweight division, with an upper limit at 77.1 kg (170.0 lb)
• The Road FC's lightweight division, with an upper limit at 154 lb (70 kg)

For the sake of uniformity, most American mixed martial arts media outlets consider Lightweight competitors to be between 146 and 155 lb (66 and 70 kg). This encompasses The Shooto Welterweight division (154 lb / 70 kg).

The UFC's lightweight division was reinstated at UFC 58 after falling into disuse following UFC 49. Sean Sherk, a former welterweight contender, defeated Kenny Florian at UFC 64, becoming the first UFC lightweight champion since 2002.

The lightweight limit, as defined by the Nevada State Athletic Commission and the Association of Boxing Commissions is 155 lb (70 kg).
